Closed type cable or the like protection and guide device

Abstract

A closed type cable or the like protection and guide device that reduces noise generation due to the generation of sliding contact sound during operation prevents entry of fine chips and wear powders of metal into the cable or the like protection and guide device. Scattering of contact wear powders, which are generated by sliding contact between components of the cable or the like protection and guide device, into the operation space can be prevented and a maintenance of the device is reduced. A cable or the like is included in a flexible support to be protected and guided from a fixed end side mounting member toward a movable end side mounting member and the entire outer surface of the flexible support except for an inlet and an outlet of the cable or the like is covered with a heat resistant tubular cloth cover.

Description

technical field [0001] The present invention relates to a cable-type protection and guide device, which is mounted on a moving part that operates while moving, such as a working machine, a civil engineering machine, or a conveyance device, and a fixed part that is equipped with a control device and an operation terminal that control the movement of the moving part. Among them, protection and guidance of cables such as electric cables that supply / transmit electric power or electric signals, hoses that supply oil pressure or air pressure, etc., and more specifically, protection against metal cutting powder, abrasion powder, etc. Enclosed cable type protective guides for entry. Background technique [0002] In the past, if a moving part that moves while moving, such as a working machine, a civil engineering machine, or a conveying device, is connected to an electric cable that supplies / transmits electric power or an electric signal, or a hose that supplies oil pressure or air p...

Problems solved by technology

[0006] In addition, it is pointed out that there is a problem that in order to smoothly bend and move the cable-like protection and guide device 500 that is surrounded by the outer frame 520 and closes the connection gap S between the middle frames 510 as described above, the middle frame A small gap inevitably occurs between 510 and the outer frame 520

As a result, fine metal cutting dust or wear dust generated from machine tools or the like enters the cable protection and guide device 500 from the small gap and damages the cables C, or enters into the sliding contact between the middle frames 510 . surface and prevent smooth bending action

And, under the structure of the cable protection guide 500, in the case of damage to the structural parts, it is very difficult to replace them.

[0007] Furthermore, the following problems have been pointed out, that is, in the state where the inner cables C are protected and guided, due to repeated bending and stretching actions, due to the friction between the inner cables C or the sliding contact between the middle frames 510 or the cables The contact wear powder generated by the sliding contact between class C and the inner wall of the middle frame 510 is scattered into the working space
